MACHINERY FOR SPINNING FIBROUS MATERIALS.

'SPECIFICATION forming part of Letters Patent No. 247,221, dated September 20, 1881.

Application filed J annary 7, 1881.

To all whom "it may concern:

Be it known that I, FRANCIS ASHER PER- KINS STERRY, of Canton, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Machinery for Spinning Fibrous Materials; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which Figure 1 is a front elevation, and Fig. 2 a transverse and vertical section, of a ring-spinning-frame spindle and its bolster and steprails as provided with my invention, the nature of which is fully defined by the claims at the end of this specification. Figs. 3 and 4 are hereinafter described.

In such drawings the spindle is shown at A, the bolster at B, the step-supporter at O, the step at D, the step-supporter cover at E, the step-rail at F, the bolster-rail at G, and the whirl at H, all being arranged as represented.

There is combined with or fixed to the whirl, and extended above it, in manner as shown, an oil-receiving cup, I, which surrounds the spindle concentrically, and at top has a lip or flange, a, projecting inward from it nearly to the bolster B, which extends through and projects below thelatter rail and into the oil-cup, the bearing for the spindle in the bolster being continued through such bolster and down into the cup. The lip on inclines downward from the top of the cup to the throat or spindle-opening of the cup, and is wholly outside of any part of the bolster, the lip forming to the throat or spindle-opening a conical trough or mouth, as shown at Z), to receive oil and carry it to the throat, from whence it passes into the cup, the cup being placed on the spindle at a sufticient distance from the rai1-viz., about three-quarters of one inch-to admit of the introduction of oil therein from the spout of an oiler. The lip or flange a of the mouth inclines downward, as shown,in order for such lip to operate to the best advantage asa means of preventing oil from being thrown out of the cup by centrifugal force when the cup may be in rapid revolution with the spindle.

The bolster has within it a tubular bushing, I), having notches c in its upper end, or projections d extending up from it, such being as shown in Figs. 3 and 4, the former of which is (No model.)

a top view, and the latter a side view, of the said bushing. The step is similarly notched or provided with projections, such notches or projections serving to prevent oil from being discharged by centrifugal force from the upper part of the bolster or step carrier or supporter whiIe the spindle may be revolving.

By having the whirl combined with and attached to the oil-cup, such whirl constitutes the bottom of the cup.

The bolster bearingthatis,the part of the bolster against which thespindle bears-by being extended into the oil-cup becomes readily lubricated throughout while the spindle may be in revolution; and by having the bolsterbearing extended some distance below and the oil-cup disposed at a distance, as described, from the bolster-rail, access can easily be had to the cup to supply it with oil through its mouth and by means of an oil-feeder.

The step is arranged within a supporter, which is chambered, as shown at O, to hold oil and to receive the step,which is simply dropped into the oil-chamber. On raising the cover on the spindle and off the step-supporter the latter may be supplied with oil when such may be necessary.

I would observe that I am well aware that an oil-cup has been fixed on aspindle and extended up within the bolster and its rail, and that such bolster has been provided with a trough extending from it above its supportingrail, and furnished with an educt or passage leading from it (the said trough) down to the bore of the bolster,whereby the oil for supply of the cup had to pass into and down through the bolster before reaching the cup; also, that the said bolster was extended above the rail, and had on its upper part its bearing for the spindle, there being in the bore of the bolster and below such bearing a'helical groove to convey oil from the cup up to the bolster-bearing, to all of which I make no claim. My improvementdit'ters from such inhaving the bolster-bearing extending below the bolster-rail and into the oil-cup, and in having the latter arranged so far below the said rail as to admit of oil being readily introduced into the mouth of the cup by anoiler, with its spout below the rail. Furthermore, my oil-cup has a trough-shaped mouth to receive oil, and it has a lip to prevent oil from being thrown out of the cup by centrifugal force, as described.

I claim I 1. The combination, with the bolster-bearin gextended below the bolster-supportin g rail and with the spindle going up through such bearing, of an oil-receiving cup fixed concentrically on the spindle at a short distance below the said rail, and provided with an annular lip encompassing the bolster-bearing and uncovered thereby, and projecting inward and inclined downward from the top of the said cup, all being substantially as set forth, the lip on its upper surface constituting a conical mouth to the cup throat or opening for reception of the bolster-bearing, and on its lower surface operating, while the spindle may be in FRANCIS ASHER PERKINS STERRY.
